Is there any way you can find out if any oops information is present? There is no oops. The system just stops responding to keystrokes other than Alt-SysRq-*. > What does Alt-SysRq-l tell us, what are the CPU's doing when the system is hung? Unfortunately Alt-SysRq-l wasn't very helpful. The output is below (captured using a serial console), starting from when I configured the wireless interface. For thoroughness I have also attached the output of Alt-SysRq-T in single-user mode, but it doesn't seem to contain anything striking. Could the problem be connected with CONFIG_4KSTACKS (which was enabled in this kernel)?
